BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel heart-shaped packaging box which is easy and inexpensive to manufacture.

[0002]

2. Description of the Related Art On Valentine's Day, White Day, etc., chocolates and other confectioneries are placed in a heart-shaped packaging box for sale. As shown in FIG. 8, the conventional packaging box includes a box body 1 in which side plates are attached around a bottom plate, and a lid 2 for the box body 1.
And both are strong as a paper product. For this reason, the sticking of the side edges around the bottom plate is troublesome, the productivity is poor, and the cost is high.

[0003] Although such a packaging box can be used as a gift for Valentine's Day, it does not hurt even if the value is a little, but as a packaging box for cheap and daily confectionery such as potato chips, Not desirable and expensive.

There is also a plastic molded product, but the molded product is more expensive than paper and the treatment after use poses a problem. Paper products are now desired in packaging boxes because of the ease of resource reuse, and paper products are easy to post-process.

Under the above circumstances, it is an object of the present invention to provide a novel heart-shaped packaging box that can be made of paper, is easy to manufacture, and is inexpensive.

[0006]

In order to achieve the above object, the present invention provides a packaging box in which a partition plate 4 along the central symmetry line P is provided between the front and rear plates 1 and 2. The front and rear plates 1 and 2 are divided into two by the central symmetry line P, and the outer peripheral edges of the divided pieces 1a, 1b, 2a, and 2b are arcuate b from both ends of the divided edge through the linear portion a. And the front and rear plates 1 and 2 of the divided pieces 1a, 2a, 1b, 2 facing each other.
Between the upper linear portions a of b, the side plate 3 is provided via a fold line r.
Part pieces 3a of the front plate 1 are connected to each other, while the pair of divided pieces 1 of the front plate 1
The side plate 3 is connected to the lower linear portions a of a and 1b through a fold line r, and the side plate 3 is divided into the divided pieces 2a and 2a.
The arcuate portion b of the outer peripheral edge of b is separated so that the tip 3b reaches the lower surface of the partial piece 3a, and the pair of divided pieces 2a of the rear plate 2 are
A tongue piece 5 attached to the side plate 3 is connected to the lower linear portion a of the b 2b via a fold line r, and the partition plate 4 is a fold line r between the two partial pieces 3a and 3a. The front and back plates 1 and 2 are connected to each other and are folded in two at the center of the front and back plates 1 and 2 to form a pair of divided pieces 1a, 1b, 2a and 2b.
Engagement pieces 6a, 6b, 7a, 7b inserted along the back surface of the mating member on the upper side of one of the divided edges and the lower side of the other divided edge.
Are continuously provided, and the pair of engaging pieces 6a, 6a
b, 7a, 7b reach the middle of the dividing edge, and one engaging piece engages with the notch 8 on the symmetry line P of the connecting portion of the other engaging piece with the front and rear plates 1, 2. It was a packaging box with a certain structure.

[0007]

The packaging box according to the present invention having the above structure is
It is a carton that can be a development view that can be punched from a single original plate (paper) as shown in FIG. 3 of the embodiment. Further, the assembly is performed by attaching the tongue piece 5 to the side plate 3 and engaging the pair of engaging pieces 6a, 6a.
The shape can be retained simply by locking b, 7a, 7b, and these operations can be mechanized. Therefore, the manufacturability is good.

Furthermore, there is a partition plate 4 in the center, and different confectionery can be put in on the left and right. Since the partition plate 4 is connected to other members and integrated, it is not necessary to stop the movement. For this reason, this box is novel.

[0009]

[Embodiment] An embodiment will be described in the order of assembling.
First, the development view is as shown in FIG. 3, and when assembled, as shown in FIG. 1, the front and rear plates 1 and 2 are heart-shaped, and the periphery thereof is covered with a side plate 3, and the center between the front and rear plates 1 and 2 is formed. The partition plate 4 is provided along the line of symmetry P.

The front and rear plates 1 and 2 are divided into two parts by the center symmetry line P, and the outer peripheral edges of the divided pieces 1a, 1b, 2a and 2b are
An arc shape is formed from both ends of the dividing edge through the straight line portion a (arc portion b).

Split pieces 1 of the front and rear plates 1, 2 facing each other
A partial piece 3a of the side plate 3 is connected between the upper linear portions a, a of a, 2a and 1b, 2b via a fold line r. The side plate 3 is connected to the lower linear portion a of the pair of divided pieces 1a, 1b of the front plate 1 through a fold line r,
The outer peripheral arcuate portions b of the divided pieces 1a and 1b of the side plate 3 are separated. Due to this separation, the side plate 3 in the developed state in FIG. 3 can be formed into a linear strip shape. A fold line r is formed in the center of the side plate 3, and locking pieces 3b, 3b are connected to both ends.

A tongue piece 5 is connected to a lower linear portion a of the pair of rear plates 2 via a fold line r, and the tongue piece 5 is attached to the back surface of the side plate 3. Be worn.

The partition plate 4 is composed of the both partial pieces 3a, 3b.
They are connected to each other via a crease line r, and are folded in two at the center thereof to be stacked at the time of assembling described later.

One of the divided pieces 1a, 2 of the front and rear plates 1, 2
Engagement pieces 6a, 7a, 6b, 7b are continuously provided on the lower side of the division edge of b and the division line of the other side 1b, 2a, respectively, and one engagement piece 6a of the front plate 1 and the rear plate 2 are provided. A notch 8 is formed in the connecting portion of one of the engaging pieces 7a. The engagement piece 6b is largely projected with respect to the engagement piece 7b, so that the engagement pieces 6b, 7b are separated from each other as will be described later.
When inserting on the back surface of b, the insertion timing of both 6b and 7b is shifted, and it is easy to insert.

In this embodiment, a paper plate having a developed shape shown in FIG. 3 is punched out, and as shown in FIG. 4, the front and rear plates 1 and 2 are bent so as to stand upright with respect to the side plates 3 and 3a, and the tongue piece 5 is formed. Side plate 3
Stick it on the back.

Then, as shown in FIG. 5, while engaging the partition plate 4 by bending it inward, the engaging pieces 6a, 6b, 7a,
7b is inserted into the back surface of each of the divided pieces 1a, 1b, 2a, 2b and locked in the notch 8. Continuing, the side plate 3 is divided into pieces 1.
A locking piece 3 along the arcuate portion b of a, 1b, 2a, 2b
b and 3b are inserted into the back surfaces of the partial pieces 3a and 3a to obtain the packaging box shown in FIG.

The confectionery may be put directly in the packaging box, but may be put in the inner box 10 shown in FIGS. 6 and 7. This inner box 10 is made of paper, and from the unfolded state shown in FIG.
The side plates 11 are erected via the fold lines r and are locked to each other as shown in FIG. Potato chips (confectionery) S and the like are put in this and put in the left and right of the partition plate 4 as shown in FIG.

[0018]

The present invention is constructed as described above and is a carton capable of punching, so that it is easy to manufacture and inexpensive. Also, the punching allows the configuration to be novel.
